Re: What's the *second* best way to keep spiders off your boat?

One more comment, make sure you check all your water, fuel and holding tank vents as spiders like to use these areas. Clean out and spray with your favorite bug killer.

My daughter has a high allergic reaction to all spiders. I use Ortho home defence once a month on the perimeter of my boat and docklines. It might not be the most environment friendly product, but, it cut the spider population dramatically. Highly effective.

If chemicals repel you try these

Here on commencement bay in Tacoma, WA, we do have spider challenges. it isn't the spiders I have a problem with, it's their WEBS! literally overnight, I will have a spider web that spans the entire width of my cockpit on the rear pulpit.... amazing creatures.

It might very well work the same way if sprayed onto boat surfaces and allowed to dry. And so far, there seems to be no finding of any toxicity to humans and mammals, it works on the bug metabolism, not ours.

Premethrin does work on spiders. The spray your linked to on page 1 is a spider spray and premethrin is the main ingredient. Just bought some yesterday to deal with the spideys in my house. They're getting good at encapsulating the chemical in a waterproof base and thus it has lasting effects in many sprays even in the rain.

Premethrin is very safe for humans, and it's what's in the malaria nets that are supposed to be used for infants in africa. Very safe for humans and dogs.

Is it, however, very toxic to cats and causes CNS toxicity, seizures and death. Safe for you, baby and Fido but not ktty.

You will need a talking rabbit with a dry sense of humor to trick Sam off the boat.

Now how to get rid of that rabbit? Maybe get some spiders.

Well I think Wombats eat rabbits, so that would take care of that, but then he will drink up all your rum, eat all your food and keep you up all night telling you stories about sailing down under so I guess you are no better off! (Just kidding sir wombat, would love having a visit from the fuzzy creature here in New York)

Or you could just find a french chef, and you might end up with some fine food! (eating the rabbit of course not wombat!)

Had to google skin so soft scientific tests. There are several. Too much of a PITA to copy links on my iPad.

Generalization is that it does work on mosquitos. However, not as well as DEET. 95%+ DEET was the only test that was 100% effective, but sos got in the 80s roughly.

You guys are so lucky. I know a vessel here that trapped an otter in the bilge. It survived for some unknown time by eating the rats that came down the anchor hawse pipe. Maybe it snacked on spiders too.

I prefer gin tonics. If being soaked in gin doesn't repel the mosquitoes, at least the quinine in the tonic will prevent malaria!
